Abstract

Des procédés et dispositifs de mesure objectifs destinés à prévoir la qualité de perception de signaux vocaux dégradés dans des systèmes de traitement/transport peuvent présenter des résultats de prévision réduits pour des signaux dégradés comportant des parties très faibles ou silencieuses. L'invention vise à apporter une amélioration auxdits procédés et dispositifs par application d'une première étape de mise à l'échelle dans une phase de pré-traitement avec un premier facteur de mise à l'échelle (S(Y+Δ), ledit facteur étant une fonction de la valeur réciproque de la puissance du signal de sortie augmentée d'une valeur de réglage (Δ), et d'une deuxième étape de mise à l'échelle avec un deuxième facteur de mise à l'échelle (Sα(Y+Δ); Sαi(Y+Δ¿i?), avec i=1, 2), ledit facteur étant essentiellement égal au premier facteur de mise à l'échelle élevé à un exposant ayant une valeur de réglage (α) entre zéro et un. La deuxième étape de mise à l'échelle peut être effectuée dans différentes positions du dispositif. Les valeurs de réglage sont réglées au moyen de signaux de test avec des indices de qualité subjectifs définis précisément.
